Radio frequency interference test device and test method

The invention discloses a radio frequency interference testing device and a testing method, which are arranged in a shielding room and are used for testing radio frequency interference of a cable. The cable comprises a to-be-tested cable and an interference cable. The radio frequency interference test device comprises a test table and a storage table which are arranged side by side. A network analyzer is placed on the storage table, and a signal transmitting port and a signal receiving port are formed in the network analyzer; a to-be-tested cable and an interference cable are arranged on the test table and are connected with the network analyzer through a PCB. And a port, which is not connected to the network analyzer, on the PCB is blocked by a blocking resistor. The cable to be tested and the interference cable are arranged on the test table in a U-shaped bending mode, the distance between the cables and the distance between the cables and the edge of the insulating plate are limited, the radio frequency in
